Equipment processing process of organic fertilizer in livestock and poultry manure


The raw materials of livestock manure organic fertilizer production line need to be collected reasonably first, and then transported to the fermentation trough in the plant area. After low temperature, medium temperature and high temperature fermentation, the eggs are sterilized. During this period, the raw materials such as urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, bicalcium, superphosphate) and potassium chloride (potassium sulfate) need to be added according to the market demand, And it needs to be equipped according to a certain proportion. In the fermentation process, we need to use the trough tipper equipment produced by Huaqiang heavy industry to provide oxygen for tipping, so that the materials on the bottom plate can be completely decomposed; After thorough decomposition, it can be used as the raw material of organic fertilizer.
organic fertilizer production line
The process of the entire organic fertilizer production line is mainly divided into biological treatment of organic waste such as livestock and poultry manure, secondary fermentation of organic waste such as livestock and poultry manure, organic material crushing, granulation, drying, cooling, screening, measurement, and packaging Waiting section and other auxiliary sections. The organic material crushing, granulating, drying, cooling, and screening section adopts closed production, which is basically dust-free; the packaging section adopts a fully automatic packaging machine, and the finished product is directly conveyed to the finished product warehouse by belt.

1. The recovered livestock and poultry manure directly enters the fermentation area. After one fermentation and two aging stacks, the odor of livestock and poultry manure is eliminated. At this stage, fermentation strains can be added to decompose the crude fiber, so that the particle size requirements after crushing meet the particle size requirements of the fertilizer granulator.
2. Pulverize the fermented materials that have completed the second aging and stacking process and enter the mixing fertilizer production machine. Before mixing, according to the recipe, add N, P, K and some other trace elements to the mixing mixer to start mixing.
3. Transfer the mixed materials to the granulator, granules pass through the dryer and enter the cooling fertilizer production machine, the materials will be sieved after reaching normal temperature, and the particles that meet the requirements will enter the coating machine to wrap the coating film and start packaging, which does not meet the requirements The granules are crushed by the crusher and then returned to the granulator to continue granulation.
4. Automatic packaging of finished products.
